Referring to .t-lije drawings, the invention comprises a casing Ahaving'a wall B which divides the casing into an oil reservoir C and afluid passageway D. The fluid passageway in this instance is threaded atits ends as at E for the reception of the ends of suitable conduits Fand G which may orLING DEVICE.v

Suitable lmeansare provided for establishin g ,communication .betweenthe passageway D and the oil reservoir C for the purpose of .admittingpressurefluid into said reservoir, and also for, delivering oil from thereservoir. into tthe passageway D. To this eiida `engine to -whichfsuchpressure fluid is being A paire of 4members H and J, preferablypfgenerally cylindrical formation, are inserted vinto the wall Bto-extend-with corresponding ends into the passageway D and attheirother .ends into the reservoir C, preferably toa point near a wallKwhich in this instance fprmsthe bottom of said reservoir. The AmembersvH `and J .in .this instance are identical ,in .all

respects and either of the ,members maybe l,used asl aconduit forladmitting pressure fluid into .the reservoir or for conveying oil lfromythe reservoir into theV passageway D,

depending upon the .manner in which the casing A vis attached to themain pressure Huid supply line, ,in other words, upon the direction offlow `of pressure fluid through the supply line.

In the present instance the/members H and J are-provided withlongitudinal conduits L-whic'h'extendfrom the lowermost ends of themembers Jto a point near'dthe'ftop ends thereof.A Communicationbetweenfthe conduits L and thepassageway D is preferably afforded" bytransverse conduits shoulders R in the'wall Bsprings S are seated on theheads P andat their other ends bear against suitable plugs T screwedinto the roof of the passageway D. The plugs T are preferablyl of suchdiameter that upon their removal from the casing free access may be hadto the members H and J. The members H and J inthis instance areadjustable, that is, they may be rotated about their longitudinal axes.For this purpose screw slots U are formed across 'In these the e'dsfofsaid 'members adjacent the head l? for'the receptionof a screwdriver orother suitable instrument, whereby said members may be mar iipulated.I

As is dwell known, ,1n any devices of this character function in anelicient manner only when the-particular grade of oil is ,used for whichthey are intended. They may be able to handle light, medium orheavygrades of oil, lbut if designed for one particular grade' of 'oi'l,ivill' n ot properly supply other grades, The reason for'this isV thatthe element'A which lgeneral-lyc'o'iitrols the flow' of o il, from thereservoir into 'the 'supply' pasing reeivir into" the pressure fluidpassagew'ztyyfIfth'isoutlet opening small diameter, obviously, only agi'fejof' oil be usedt However, "a 'shalloultletopen-ingprecludes'tlieluse of of oil, and, 'ontliey o'ther hand,

1s, .of courte, understood, the present device is largely `de endent forits efficient functioning upon the pulsations which occur in the'pressure fluid supply due to the admission and cut-oil' ot pressurefluid in the` engine to which such pressure fluid is being supplied. Thepressure fl'ui'd admitted into the oil reservoir creates a pres- BESTAVAILABLE COPN In Figure ,3 theV member i is illustrated' as being.substantially in the same'p'ositionxas that shown' in Figures 1- and 2,.that is', the

In this showingthe memberlI-I isrotated so that its conduit O eXtend'setrans- 'verselyto the flow ofpressure fluid through the passageway and the mem'b'er- J is movedapproximately a'neighth otlfa turn. In these positions otthe'membersI-If andJ a. minimum amount of pressure fluidz'will beadmitted into the reservoiivand vdue to the smaller area of the outletlopening of the conduit Oin the member J exposed-t the sucking actionofthe pressurefluid; a smaller quantity of oil will be delivered to thepressure fluid.

In Figure 5 both-'the members .H-an'd' J are moved aproximately one eilith? of a turn' from the full on positiom't us Sh'ov'v'- ing stillanotherl means of reducing the flow of oil trom the reservoir. In thepositions ot the membersI-I 'and J illustrated in Figure 6 it will benoted that both of the transverseconduits O occupy a positionapproximately at right angles to the direction of flow' of the pressurefluid through the passageway D. In this position of the members H and 'Jonly a mini'- mum quantity of oil will'be supplied to the lpressurefluid.

In the drawings, only a few ot the positions which the members" H and Jmay occupy tor regulating the flow of oil from the reservoir are shown`It is, of course, to be understood that thesem'embers may be 'adjustedrto any intermediate posit-ions and that these showings are intendedmerely for illustrative purposes. v

IVhile, as hereinbe'fore stated, the present invention is primarilyintended to accomlUO mo'datedifferent' grades 'of-1oil *i t 'willgbenoted" fthat [by reasonof the' adjustable# fea'- 'ture 'embodied' ini".the l id'evice, a' greater.:l or lesser amoun'tv of'anyfgra'de may bedelivered from-f the reservoir".to1su' "l i immediate needsw t Bymeansof this-invention, I am enabled to use unusually large outlet openingsin the conduits O, thus entirely eliminating clogging of the oildelivering conduits as so frequently occurs in similar devices in whichonly outlet openings of small diameter may betused.

In the modification shown in Figure 7 members V and W are insertedthrough the wall B of the casing A. The members V and WV are in manyrespects similar to the members H and J in the preferred modication, butdiffer from the members H and J in that they are provided withrelatively larger longitudinal conduits X in which may be inserted theends of wicks Y. The wicks Y are preferably of such length that aconsiderable portion thereof may rest on the bottom of the reservoir Cas illustrated, so that said wicks will be at all times inmersed in theoil irrespective of any position which the device may occupy inpractice. The. members V and lV are also adjustable to various positionsin the wall B for regulating the delivery of oil into the pressure fiuidstream. The members V and W like the members H and J in the preferredmodification are also symmetrical, thus rendering the device reversiblein the pressure fiuid supply line.

In this modification, oil will be supplied by only one of the wicks Y,in the present showing, by the wick Y in the member lV. The wick Y inthe member V in this instance serves as an air filter to prevent theconveyance of any foreign matter which may be carried by the pressureHuid, thus also insuring a clean supply of lubricant at all times andeliminating the necessity of frequent cleansing of the reservoir C.

In the modification illustrated in Figures 8 and 9, a member Zsubstantially like the members H and J of the preferred modification isinserted in the wall B for the admission of pressure fluid into thereservoir C. In this instance, another member b, resembling somewhat themember Z, is also inserted in the wall B for delivering oil from thereservoir into the passageway D.

Suitable means are provided for atomizing the oil issuing from theoutlet opening of the transverse conduit o. To this end an impeller d,mounted on a shaft e journaled in the member Z), is arranged to rotateacross the outlet opening of the conduit c. The impeller d may be of anysuitable type and is rotated by the pressurefluid fiowing through thepassageway D, irrespective of any position which the member o, andconeEsT AVMLABLE com -sequently the1 =imp`ellercl, 1 may; occupy. withrespect'xtoftlie passageway D: The members Zfand' binfthis-instance---are .also capable of adjustmentto positions 'suitablefor supply- -iing'fa required amount-of oilto the pressure fluidflowing-'through the.- passageway D.
